One caution when installing dropped spindles. The ground clearance under the front of the car will be reduced by the amount of the spindle drop. If you have 4 inches of clearance and put in 1 inch drop spindles, your ground clearance will be reduced to 3 inches.
The approach to avoid this is to "Z" the frame behind the front wheels. This allows the body and sheet metal to drop while maintaining the front ground clearance, but the engine moves up closer to the underneath of the hood.
